17th July, and the five days ending 17th August. The average 
daily excess of temperature during the 53 days ending 22nd August 
was 4^ °. From the 23rd August until the 17th September low 
temperature generally prevailed, the average daily deficiency being 
equal to 3^°. A warm period, however, set in on the 18th Sep- 
tember, and lasted until the end of the month. 
The mean temperature of the quarter was 61° - 8, and exceeded the 
average for the corresponding period in 105 years by 2°*1. In July 
the mean was 65 0- 9, and 4 0, 3 above the average. Since 1841 the 
mean temperature of July has only twice been as high as it was 
last quarter ; it was 68°-l in 1859 and 67°-5 in 1868. The mean in 
August was 63° - 7, showing an excess of 2°"9 ; whereas in September 
it fell to 55 0, 8, and was 0 o, 8 below the average. The mean tem- 
perature of the quarter at 47 stations of observation ranged from 
55°-7 at North Shields, to 63°-3 at East Tilbury. 
The rainfall during the quarter at the Greenwich Observatory 
was but 5 - 3 inches, and was 2-2 inches below the average in the 
corresponding three months in 61 years. In July only 0 - 7 of 
an inch of rain was measured, showing a deficiency of nearly 
2 inches ; in August and September 2-0 inches and 2 - 6 inches were 
respectively measured, neither amount differing considerably from 
the average. The rainfall at all the stations of observation between 
latitudes 50° and 55° averaged 8 - 5 inches, against 10*3 inches in 
the corresponding quarter of last year; between 51° and 52° the 
average fall was 7 - 3 inches, whereas between 53° and 54° it was 
9-5 inches. The measured rainfall during the 13 weeks ending 30th 
September in each of nineteen other large English towns furnish- 
ing returns exceeded that recorded at the Greenwich Observatory ; 
it ranged from 6 - 4 inches in Leeds, to 10 - 7 and 13 - 0 inches in 
Plymouth and Bristol. 
During the first nine months of 1876 the amount of rain mea- 
sured at the Eoyal Observatory, Greenwich, was 13*7 inches, and 
was 4*5 inches below the average amount in the corresponding 
period of 6 1 years.
